carends while at the same time so locating the connections between the oars and between the cars and vestibule that a proper angular relation between the same may be maintained at all times.

A further and more specific object of the invention is to provide a structure of this character which permits the car-connecting pivot to be arranged in very close proximity to the king bolt forming the pivot for the' supporting truck thereby insuring a reduced throw of the truck-supported car and providing an arrangement in which the normal angular deflection of the cars and vestibule varies but slightly.

These and other objects I attain by the construction shown in the accompanying drawings wherein, for the purpose of illustration, I have shownl a preferred embodiment of my invention and wherein:

Fig. 1 is a plan view of an articulated car connection constructed in accordance with my invention;

Fig. 2 is a view partially in elevation and partially in vertical section through the connection; and

Figs. 3, 4, 5, and 6 are diagrammatic views illustrating various ty es of cars and the method of employing t e same.

Referrin now more particularl drawings, t e numerals 10 and 11 in 'cate adjacent car ends which may hereinafter be referred to as the supporting and supported car ends respectively.

The supporting 'car end has associated therewith a truck 12 havin a flanged pivot disc 13 having side and hu an es 14 and 15 defining an annular track 16. e annular track 16, which may be suitably oored with a wear or bearing plate 17, receives an annular pivot iiange 18 projecting downthe car.

to the wardly from the central frame member of Through this frame member and the truck bolster 12 projects a king bolt 19 which is keyed asat 20 to prevent its rotation with relation to the truckand has at its upper end a transversely-extending arm 21 operating over the upper surface of the frame member of the supporting car end. This arm may be directly secured to the king bolt but is at present illustrated as having a hub portion 22 formed in its upper surface with a squared socket 23 to receive the head 24 of the bolt.

The central frame member of the supporting car has a projection 25, provided in its uppersurface with an annular bearing channel 26 loored with a bearing or wear plate 27, the upper surface of which is slightly arcuated so that it may provide a semi-universal support for an annular bearing flange 28 formed upon the lower surface of the frame member of the supported car end. The pro jection and the frame member ofthe supported car are apertured to loosely receive a short king bolt 29, the upper end of which is provided with a head 30 seating in a socket 31 formed in a casting32 ,rigid to the bottom 33 of the vestibule. Between the casting 32 and t-he bottom of a, recess formed in the upper surface of the frame member of the supported car through which the king bolt extends, the king bolt is surrounded by a spring 34 which in installation is compressed to support the weight of t-he drum vestibule and possible passenger load. Casting 32 has a radial arm 35 connected with arm 21 of king bolt 19 by a link 86.

It will be obvious that a construction such as hereinbefore described will permit the necessary transverse and longitudinal oscillatory movements between the car ends 10 and 11 and it will of course be obvious that the spring 34 will act to maintain the drum in a substantially vertical position with respect to the car end 11 and to at all times resist its movement from such position. In order that transverse oscillation of the cars may not become excessive at the upper portions of the cars and thus cause too great a swaying action and a resultant binding of the drum against the usual drum guide,- I mount at the upper-end of the car end a bracket 37 I* vand at the vupper end ofthe car end 11 a bracket 38. Each bracket 37 and 38 is apertured as at 39 for loose passage of a bolt 40, the head of this bolt abutting the outer face of bracket 37 and the bolt being of sufficient length to project well through bracket 38. About the bolt, between brackets 37 and 38. a spring 41 is disposed and about the bolt between bracket 38 and a seat 42 carried by the threaded end of the bolt a second spring 43 is disposed. Springs 41 'and 43 act to resist transverse oscillation of the upper portions of the car ends with relation'to one anotherand to restore these -car endsjtotheir proper position in event. of any displacement thereof. The loose mounting of the 'bolts in the bracketspermits the necessary longitumultiple between such cars'.

dinal angular movements.

Employing car mountings of this character, cars may be conveniently constructed in four different typeswhi'ch arereadily combined to produce a train. Such" types I have indicated by characters A, B, C and D in the semi-diagrammatic views of Figs. 3 to 6.v Car A has one-plain end and Va" supporting end l0, while car B has one plain end and a supported end 1l. Car C, which is intended for use between cars of the type B, has two supporting ends 10 for the reception of the supported ends 11 of the vtype B cars.- The type D car is pro-M lvidedwith both supported and supporting ends and may be employed ybetween cars of type A and B or may be employed in It will be noted thatby the construction above described an arrangement is provided wherein the vestibule may be supported'by one car which is in turn supported from another truck-supported car and at the same time the supporting truck and the support of the vestibule-.carrying car may be arranged in such close proximity that the angular displacement in rounding curves will not be sufficient to cause any binding of the vestihule. Thus a structure of this character emv'bodies the advantages of those structures wherein both cars are supported from a com-' mon truck and further, the advantages of that type where-one of the car ends is made cars, a truck supporting one thereof, a pi'v- 'otal connection between the car ends disen-l gageable'byrelative vertical movement thereof, a vestibule for connecting thev cars-dis- -meanssupporting the vestibule and resisting relative vertical movement of the car ends, and means positively limiting separation of the vestibule and the first-named car end.
